Asterix Exists for One Reason

To fix the biggest problem in healthcare: there are not enough doctors, and the system can no longer keep up. Millions of patients wait weeks for appointments. Millions more are stuck on hospital waitlists. Health conditions that can be prevented are missed and go unnoticed.

Asterix is building the only viable solution:

A new model of care where highly-qualified doctors are augmented by AI: safely, consistently, and measurably. The DoctorOS, our emerging clinical platform, is becoming the backbone of modern healthcare delivery. We combine rigorous clinical leadership, technology adapted for real-world care, and AI tooling that makes doctors 10x more productive. We are backed by Entrepreneur First, recently closed an oversubscribed funding round, and live with some of the largest healthcare providers in the UK, generating revenue and expanding fast.

Your Mission will be to bring clinical insights into product decisions, as we build safe, production-ready clinical AI

This role is a unique role for doctors that are passionate about technology and solving thorny problems. As our Founding Clinical Product Engineer, you will help architect and own clinical development in the DoctorOS and our AI systems. You will design, build, and ship product-critical clinical intelligence used every single day by doctors delivering patient care.

By joining us now, you will define our tech stack and decide what we need to scale. Our current tech stack is

Frontend: React 19 with TypeScript
Backend: AWS serverless — Lambda, API Gateway, DynamoDB, and S3
Authentication + Database: Supabase
Tooling: Playwright for testing, Tailwind for styling, Radix UI for components

You will work on:

• The entire Product/AI lifecycle: inference pipelines, retrieval, fine-tuning, evals, safety mitigations, and monitoring.
• Clinical-grade eval & safety infrastructure: hallucination detection, error monitoring, model governance, incident tooling and system-level guardrails.
• MLOps & infra: reproducible training pipelines, CI/CD for models, audit trails, versioning, and data lineage.
• Human-in-the-loop clinical validation: working directly with doctors and our clinical leads to define acceptance criteria and run prospective evaluations.
• End-to-end shipping: design → prototype → deploy → measure → iterate.
• Future team growth: help hire the next engineers and shape the technical culture from the ground up.

There is no partition between research, engineering, and product…… here you are all three.

Who You Are

You should be a doctor that cares deeply about modern technology. Beyond that, we don’t care about pedigree. We care about what you’ve built and how you think.

You thrive when:

• The stakes are high and the feedback loops are tight.
• The constraints are real (safe, compliant clinical environments).
• You own outcomes end-to-end.
• You’re responsible for systems that must work and must be trustworthy.
  
  

You’ll be a great fit if you have:

• Been a founder or founding engineer
• Experience with LLMs, model evaluation, monitoring, or MLOps.
• A track record of shipping ML or production systems in high-stakes environments.
• High agency and product intuition: you chase impact, not tickets.
• Strong judgment around risk, safety, and quality in real-world deployments.
• Experience working full-stack (infra ↔ data ↔ product).

Bonus if you:

• Have worked in regulated environments
• Built software/AI as a medical device
• Have shipped tools used by clinicians
• Have founded or been early at a startup
  
  

Culture- The Asterix Way

We are a small, deeply ambitious, and intensely collaborative team. We move fast because what we’re building matters.

Humble

We assume we’re wrong until the data or a clinician proves otherwise. We default to curiosity. We ask questions. We help each other level up.

High-intensity - Founder mentality - No corporate wannabe’s

You don’t wait for permission. You push problems to resolution. You act like an owner of the mission, the codebase, the infrastructure, and the culture.

Solving one of society’s biggest problems won't happen in a 9-to-5. We need our team to understand we will always ask for that little bit extra. We work hard, but with intention.

Joyful energy

We take the work seriously but not ourselves. We laugh a lot. We celebrate the small wins. We show up with energy, optimism, and kindness, and back each other completely

If you bring enthusiasm and momentum, you’ll fit right in.

In-person by design

We work together, shoulder-to-shoulder in London. This makes us faster, tighter, and better and it makes the journey more fun.
